Raspberry Pi Inverter Auto-Setup for PI30 / PI18

Auto-setup project for Raspberry Pi inverter monitoring and control with WatchPower-like and SolarPower-like workflows.

This project helps set up PI30 / WR1 and PI18 / WR2 inverter environments on Raspberry Pi with MQTT, systemd, and either a built-in UI or an external UI.

Features

• Supports PI30 / WR1
• Supports PI18 / WR2
• MQTT integration
• Generates systemd service files
• Supports built-in UI
• Supports external UI
• Creates installer configuration and activation commands
• Uses device-based service names
• Consistent latest_json handling from installer to builder services

UI Preview

WR1 / PI30 UI

WR2 / PI18 UI

Project Structure

• PI30 / WR1 → watchpower-like
• PI18 / WR2 → solarpower-like

Quick Start

PI30 / WR1

python3 setup_pi30.py

PI18 / WR2

python3 setup_pi18.py

Installer Flow

The installers ask for:

• device / USB port
• device name
• MQTT on/off
• MQTT host / port / username / password
• poll interval
• UI target directory
• UI mode
  • built-in
  • external
• UI port for built-in mode

Current Status

Verified in isolated test runs:

• built-in mode for PI30 and PI18
• external mode for PI30 and PI18
• service slug generation from device name
• reader / builder / timer service generation
• UI service only for built-in mode
• installer command script generation without automatic execution
• consistent latest_json handling from installer to builder services

latest_json Handling

The current project logic uses device-based latest JSON files:

• readers write to /home/pi/wr-logs/<device_name>_latest.json
• builders receive that path through Environment=LATEST_JSON=...
• state builders keep a fallback to WR1_latest.json and WR2_latest.json
